Sacramento police say officers responded to the scene a little before 3 a.m. to investigate a reported collision involving a person and a car.

Medics had pronounced the person dead at the scene by the time officers arrived.

The area of A Street between 16th and Ahern was closed for several hours while authorities reconstructed the scene. Police said the driver is cooperating with the investigation.

Later on Monday, police investigators released more details about the incident. It appears that a man tried to take control of a car where a woman was sleeping inside, police say. While trying to get away in the car, the woman ran over the man – killing him.
